Here's a few I made some time ago. I added small glass flower beads and some silver shapes (heart & flowers) that I made from PMC. I reinforced the shapes so if they caught on anything they wouldn't fall off. I never had any problems. You can find tons of peyote patterns at www.about.com in the beadwork section and also at www.bead-patterns.com (free ones). Remember to work the ends of your threads to the middle so you don't have fraying on the edges.
ohhh i like your rings very much! i never thought of adding shapes to them!!!! i love'em! .. I usually knot my 2 ends and add a drop of super glue to the knot to secure it? so after the 2 sides of the ring are weaved together - you just take each end and weave to the middle then cut the remaining thread? I guess i took the lazy route
